Hardware Design of Video Conference Terminal Based on DM642SUN Kai YANG Hui College of Electronics and Information Engineering, South-Central University for Nationalities, Wuhan 430074Abstract:A video conference terminal based on TMS320DM642 was proposed, mainly including minimum system module of DM642, power module,video input module,USB transport interface module. Meantime, the debugging process of every hardware module was introduced. Terminal reduced the burden of the computer CPU by means of using hardware video compression encoding,and it can transmit highdefinition video signal, realizing the stable portable video conferencing terminals of flexible mobile platform.[著者文摘]
